There was a post to questions at freebsd.org regarding recommendations for
HA setup of FreeBSD.  The post got no responses.

While overcomplicating the rc system is A Bad Thing(tm) in my opinion, I think
there is some severe lacking in this area.  i.e. _something_ needs to be
implemented.  Linux HA/OCF seems to share a lot with the existing rcng
system, and seems to be the most logical system to try to use.

I work with Brian.  Knowing our requirements, we're going to set this stuff
up, because we need it.  Both Brian and I would like to contribute our
improvements back to the community.  If we could get a consensus on what
approach to the problem is most likely to be accepted by the community,
then we _will_ be doing work over the next few months that will benefit
FreeBSD, and we _will_ be contributing it back to FreeBSD.

So, the upshot of this discussion is that Collaborative Fusion is going to
be throwing developer resources at FreeBSD HA.  We'd like feedback from the
FreeBSD community on how we can best do this so that it can be integrated
back into the FreeBSD source tree.  We've already done _some_ research and
we're looking for input.
